Megadroughts Expanding Globally as Climate Warms, New Study Finds
A groundbreaking study published in Science has revealed that megadroughts severe, long-lasting dry spells have been increasing in size, duration, and intensity over the past four decades. Researchers found that the total land area affected by multiyear droughts has expanded by 50,000 square kilometers (12 million acres) annually, signaling an alarming trend driven by climate change.
A Comprehensive Global Drought Catalog
For the first time, scientists have compiled a global catalog of long-term drought events since 1980, assessing their effects on vegetation and ranking their severity. The research, led by Liangzhi Chen of the Swiss Federal Institute for Forest, Snow, and Landscape Research WSL, identified 13,176 individual droughts lasting longer than two years between 1980 and 201...
